[VA/VE Case] Transition from Welded Nuts to Riveting Method
There are numerous achievements in cost reduction and quality improvement due to changes in joining methods!
We would like to introduce a case where cost reduction was achieved by switching from welded nuts to rivets. A designer consulted us, saying, "The drawings indicate welded nuts, but is there a more efficient method?" After a detailed analysis of the strength and functionality required for the product, we found that changing from welded nuts to rivets would not pose any quality issues. Therefore, we proposed a change to the riveting method, which would reduce the welding process itself. [Case Overview] ■ Before - It was believed that there was room for improvement in the man-hours and costs associated with the welding process using the current welded nut method. ■ After - The elimination of the welding process led to a reduction in man-hours and achieved cost reduction. - Since the consultation was from the design stage, a smooth specification change was made possible. *For more details, please download the PDF or feel free to contact us.
